The spaced'recessesishown in'Figs. 1-.8 represent the Fpreferred formpf the apertures H. The apertures may, however, take othenforms.

Vis thus effected.

3 apertures II are in the form of openings which lie wholly within the marginal edges of the Wing portions I4 and which may be of rectangular or triangular outline.

The device is constructed of flexible sheet material such as sheet steel of say 24 to 26 gauge. Thus, the device may be stamped or cut as a single piece from a sheet of material with the body, Wings and arms of the device in coplanar relationship. As thus formed, the device can be conveniently accumulated in uniform stacks and packaged. The arms I and I6 are flexible and when the device is used, they are easily bent in any desired manner to accommodate the particular thickness of the insulation or other material or object to be held.

Referring particularly to Fig. 1, the device of the invention is shown supporting sheets 20 of insulating material, such as mineral wool or cork, against a ceiling 2| Itwill be observed that the fastening device is secured tothe ceiling 2I by a suitable adhesive 22. In applying the device as shown, the arms I5 and I6 are bent at right anglesto-thebody portion I3 and the body portion and wing portions I4 are dipped in a supply of adhesive and then pressed against the ceiling with the arms extending downwardly. Owing to the apertures, the adhesive not only covers the surface of the device which is pressed against the ceiling but also forms a continuous binder film along the edges of each aperture. A firm bonding of the device to the supporting surface Furthermore, the apertures facilitate the evaporation of solvent from the adhesive., of the apertures inwardly and insures a firm bonding in minimum time. The sheets of insulation or other material to be applied are then pressed against the outwardly bent arms I5 and I6 0f each device. The arms penetrate the sheets and the portions of the arms whichextend beyond the lower face of the sheets are readily bent parallel to the face, as shown clearly in Fig. 2.

An embodiment of the-device of the invention adapted for use as a support for pipe or conduit as well as for insulation sheets is shownin Fig. 4. Arms I5 and I6., vwhich are shown bent at right 4angles to the body portion, are provided with notches 25 and 26, respectively, extending inwardly from opposite edges thereof. As shown in Figs. 6 and 6a, when the arms I5 and I6'are bent into a loop, notches 25 and 26 can be interlocked to form a pipe hanger in which a pipe 30 may be inserted and securely supported. If desired, additional notches are conveniently made in arms I5 or I6, or both, whereby pipe or conduit of various sizes may be firmly held in loops vformed by interlocking complementary notches.

lthe penetration of the arms through the board l.

or sheet to be supported. Fig. 8 shows an embodiment of the invention, in which the arms I5 and I6 are provided both with points 35 and 36 'and with notches 25 and 26.

Referring particularly to Figs. 11 and 11a, there is shown the manner inwhich the device I2 having apertures I'I of the preferred form, i. e., re-

cesses extending inwardly from the marginal .edges of the wingl portions I4, may` be most ,eonomially cutfrom. a continuous. parent .Saget The adhesive dries from the edges 4 of material such as sheet metal. It will be observed that when cut in the specific manner illustrated in Fig. 11, the length of the arms I5 and I6 is equal to the aggregate width of the body portion and the two opposed wing portions.

It will be apparent that various modifications in the structure of the fastening device illustrated may be made without departing from the scope of the invention as defined in the appended claims and it is therefore intended that the drawings and the foregoing description shall be interpreted as illustrative and not in a limiting sense.

I claim:
